Summit Rancho Bernardo—a sprawling, brutalist-style corporate campus built in the 1960’s—recently underwent major renovations. Although the campus’ Central Plant had become inefficient, the building itself maintained advantages: long-term durability, high ceilings, and a location in the heart of the campus. Leveraging this, the team transformed it from a utilitarian fortress into an attractive campus centerpiece for fitness and social activities.The Central Plant Club’s exterior renovation maintained much of the existing angular concrete panels while new openings were added to make it an occupiable space. By breaking up the panels into palatable sections, the facade additions highlight the concrete’s rhythmic pattern while adding interest and transparency. With its newfound visual richness and valuable resources, the Central Plant Club is a surprisingly exciting space for the campus.
